Can anyone tell me how to adjust the proximity switch? My new table top is centered on powerstick. When i home x and y using proximity switches...c3 command... it zero's to about half inch off table top. This is causing my Value limits to warn me about cutting larger than limits on a 48 x 48 perimeter practice cut. It cuts fine when i ignore VL warning... Not sure what i doing wrong. any help would be appreciated

thanks,
JJ
